    The device shown in Figure 1 is adapted to be mounted on a wheeled vehicle, in particular a motorcycle. For example, the device comprises means at the rear able to cooperate with a system for attaching a support mounted on the handlebar of a motorcycle.
    The device comprises: - a screen 1, an on / off button 2 - a button to confirm a position 3 and / or a choice (in a menu) and / or to open a submenu or a page of a menu or menu a submenu a file search and / or program button 4, and left / right command buttons and / or up / down buttons to select options in either mode of the file or program.
    The device also comprises: a means for receiving position information from a satellite, for example a GPS; a memory 11 able to contain a particular route with details as to the crossroads or crossings; a means 12 for processing the position information received to determine at least the changes of route to be made to follow the desired route; a rechargeable battery 13 for powering the GPS 10, the memory 11, the processing medium 12, as well as the other electrical power means, a connection 14 for recharging the battery 13, a connection for charging a route in the memory 11, this advantageously sealed connection being preferably of the wireless type, - a connection 16 for receiving information or information of the motorcycle, for examplespeed, acceleration, distance traveled, the direction, thispreferably sealed connection is preferably of the wireless type, - a receiver 16bis of various information from third parties or third party transmitter systems, such as by telephone system (GSM), radio stations, communication systems for example using Bluetooth technology, the received information being for example information about the presence and / or the position of one or more radars, the presence and / or position of work, information about maximum speeds, information about the proximity of one or more schools, traffic information (traffic jams, accidents, "traffic"), weather information, etc.
    a link 17 to the screen 1 for sending signals from the processing device 12 to the screen 1,
    Advantageously, the entire device is waterproof or substantially sealed.
    The processing means 12 comprises instructions 120 for determining an anticipatedposition of the vehicle according to the following parameters: vehicle speed 121, determined vehicle position 122, vehicle direction 123 and anticipation time 124, and instructions 125 to search for a change of road taking place in the portion of the route between the position of the vehicle and the anticipated position of the vehicle, this search being carried out in the memory 11. The speed of the motorcycle and / or the direction of the motorcycle can be reduced by a signal or signals from the motorcycle itself, the position of the motorcycle, GPS analysis of the displacement made during a period of time, etc.
    The processing means 12 includes a clock 126 for controlling the periodicity of the determination of an anticipated position or the timing of a new determination of an anticipated position.
    The processing means comprises instructions 127 for determining a duration of time greater than half a second between the determination of two anticipated positions, this duration being between 0.8 seconds and 2 seconds. According to a variant of an embodiment, the determination of this duration takes into consideration the speed of the vehicle, the type of route portion being treated, etc.
    The processing means includes instructions 128 for determining a point or area of a desired route corresponding to the position determined by satellite and / or corresponding to an anticipated position. These instructions determine a point or a desired ID route area by orthogonal projection determination of the position determined by PS satellite and / or corresponding to an anticipated position on one or more segments '', S2, S3, S4, etc. of the adjacent ID route of saidposition or on one or more straight lines linearly extending the one or more segments, (see FIG. 4). The means thus determines, for example, the point A1 on the segment S3, the point A2 on the extension of the segment S4 and the point A3 on the extension of the S2 segment.
    The means then determines by comparison instructions the projected point closest to the GPS point PS and determines the distance D between the point PS of its projection Al on the route. If this distance D is greater than a predetermined distance (for example greater than 100 meters), the processing device sends to the display device 1 an arrow showing the general direction to follow to reach the desired route.
    Depending on the position of the bike (GPS point PS or its projection on Al on the route ID) or an anticipated position of the bike on the route, the means is programmed to determine the general direction of the road or road. itinerary to follow. For example, the processing means determines a current position of lamoto or a position close to the current position of the motorcycle, and the position of lamoto on the route after traveling a distance of more than 2km, for example more than 4km , in particular more than 5 km, for example from 10 to 20 km. From these two positions, the processing means determines a general direction from the current position to the future position. The processing means then sends a signal to the screen or display device, for example in the form of an arrow representing the general direction of movement to reach the future position. Such an arrow is useful to facilitate the rider to anticipate his movement, but also to find his way back if he has lost the predetermined route. Lemoyen treatment also takes into consideration the direction of advancement of the motorcycle or the general direction of the motorcycle, for example when the motorcycle is at a standstill.
    According to one variant, the processing means determines an arrow or general direction of movement at medium distance (for example the general direction of displacement relative to a future position 2 to 8 km distant from the substantially current or actual position of the motorcycle) and a arrow or long-range general direction (eg general direction of movement in relation to a future position 10 to 20 km or more away from the current or actual position of the motorcycle).
    This arrow or these arrows thus give a general trend of traveling along the route or a general tendency of movement to reach a point of the route.
    According to another variant, the processing means determines a general tendency of short-distance movement, for example with respect to a future position of the motorcycle located less than 500m, advantageously less than 200m from the current position of the motorcycle.
    To ensure greater reliability in the selection of the projection point, the different points of projection of the PS point on the segments are analyzed according to the position history and the speed of the motorcycle. In the case of a hairpin, this analysis makes it possible to take into consideration point A5 of the route farther away from the point PS and to reject the point A6, since it is possible that the motorcycle has traveled more than x meters from the point Previously determined, (see Figure 5).
    Knowing the position of the motorcycle substantially correct on the route, ondetermine the anticipated position of the bike, that is to say the position of the bike for example 1.5 seconds later (anticipation time).
    By analyzing the path and memory information, it is possible to determine the changes in direction stored in the path traveled during the waiting period.
    The history of at least a part of the route traveled before the point determined by orthogonal projection of the position determined by satellite and / or corresponding to an anticipated position also makes it possible to determine the segment or segments on which the projection of a new GPS point can be determined (for example on the one or both segments of routes according to the segment on which the previous GPS point was projected.
    The route is advantageously stored in the form of a succession of segments of length less than 50 m, advantageously less than 25 m, preferably less than 15 m, for example about 10 m.
    The processing means includes instructions for displaying a direction change and maintaining the display and for maintaining the display for a period of time sufficient to effect the change of direction.
    Preferably, the processing means includes instructions for maintaining the display of the change of direction until the means for processing satellite position information relating to a point corresponding to a point of the route subsequent to the point of change of direction. direction.
    The processing means advantageously comprises instructions for recording a route. This then allows a driver to establish a route or a file, which is adapted to be reworked for example on a personal computer.
    FIG. 7 represents a route I defined by a series of points Pi.
    The route is thus defined by a kind of table giving for the different successive points of the route the coordinates. This table is for example contained in a memory of the device or on a support readable by the device or via transmitter / receiver means, this table is readable or accessible in a central data bank.
    After searching for the estimated position of the device and thus the driver on the route (Px), the processing means determines a series of general directions to successive points of the route towards which the vehicle is traveling. The successor points are, for example, 25 m apart, the first point being 25 m from the estimated position of the conductor. The series of general directions D1, D2, D3, D4, D5, D6 is expressed at least by an angle measured with respect to the rectilinear direction of motion of the DRV vehicle. This rectilinear direction of motion is determined by the processing means by seeking the direction of movement substantially tangent to the portion of the path of the route extending 5 to 10m after the point corresponding to the position of the device or ductuctor. The processing means determines, among these general directions, the general directions forming an angle between -15 ° and + 15 °. For example, DI and D2 are directions with an angle of less than 15 ° for the point Pi, D3 representing an angle more than 15 °. For the point Pj, the directions are D1, D2, D3, D4 and D6, the direction D5 being greater than 15 °
    The processing means determines for the general directions of inclination between + 15 ° and -15, the directions between the position of the driver and the first general direction of more than 15 ° or less than 15 ° inclination with respect to the direction rectilinear moving DRV. From these determined general directions, the processing means determines the extreme directions, namely DI and D2 for the point Pi, and the directions DI and D3 for the point Pj.
    If the difference in angle between the extreme directions is less than 10 °, the device determines the mean direction between the extreme directions. Thus, for the point Pi, for which the extreme directions DI and D2 differ from each other by less than 10 °, a median direction DM is determined. This median direction is then sent to the screen so that it is indicated as a directional arrow.
    If the angle difference between the extreme directions is more than 10 °, the processing means determines the extreme direction corresponding to the furthest point of the position of the vehicle or the device. Thus, for the point Pj, the processing means will select the direction DI because it is the direction corresponding to the point closest to the position of the device Pj.
    In a variant, when the general direction DI or D2 is more than 15 °, the processing means emits a sudden change of direction signal, for example an arrow appearing intermittently on the screen or appearing in red color or other.
    This direction arrow of close movement serves to somehow show the direction of close movement or in a very close time (less than 1minute). Such an arrow is in a sense a directional eye or a means to give an almost instantaneous movement tendency.
    FIG. 8 schematically represents an itinerary at least defined by a series of Pn-m crossing points, ... Pn-2, Pn-1, Pn, Pn + 1, Pn + 2, ... Pn + k.
    The different points of passage are advantageously contained in a table of a memory or a medium that can be read by the device. For each crossing point, the table assigns a clue, coordinates, a general direction to the next waypoint, the distance between two successive crossing points of the route, the importance of the waypoint (depending on the curiosities, city, highway, etc.), feature (s) (directional change), and at least one signal or flag indicating whether the vehicle has already passed through the clearing point.
    The processing means searches for all the crossing points situated in a circle of radius R calculated as a function of the speed of movement of the vehicle. The circle is centered on a point Z corresponding to the position of the vehicle, in this case the vehicle has deviated from the path of the route.
    The processing means will now search for directions to a route point of the route.
    The processing means determines the points of passage through which the vehicle has not yet passed which is in the circle of radius R, namely for Figure 8, the points of passage Pi + 1, Pi + 2, Pw and Pw 1.
    The processing means then determines the different general directions of displacement to reach the different crossing points located in the circle and by which the vehicle has yet passed, namely for the example of FIG. 8, the commands Dpi + 1, Dpi + 2, DPw and DPw + 1.
    The processing means searches for the closest point of passage (here Pi + 1) and classifies the different waypoints according to their distance from point Z, here Pi + 1, Pi + 2, Pw + 1 and Pw. The processing means searches whether the nearest clearing point is the next waypoint directly to the last waypoint through which the vehicle passed.
    If the nearest point of passage is the point of passage following the last point of passage, the processing means emits a signal to display on the screen a general movement arrow to this point (Pi + 1). Advantageously, the average treatment determines by a cartographic examination whether a possible road orconvention to the vehicle exists between the point Z and the point Pi + 1.
    In the case where no road suitable for the vehicle exists between the point Z and Pi + 1, the processing time resumes the processing step with the second nearest clearing point of the point Z, ie the waypoint Pi + 2 in the case of Figure 8.
    In the case where the nearest crossing point is not the crossing point following the last crossing point through which the vehicle has passed, or in the case where the driver decides to go directly to a more remote waypoint (eg to catch a delay), the processing means determines the general direction towards this point. For example, if the driver decides to go as fast as the point Pw + 1, the processing means will determine the general direction of movement of the point Z to this point Pw + 1. However, the means of treatment determines whether a suitable direct route for the vehicle exists towards this point. If such a route does not exist (for example by the presence of a mountain or lake), the processing means searches whether a route exists towards the point of the route preceding the point Pw + 1. If so, the means of treatment will indicate as a general direction the direction towards this point Pw. There is still no direct route to this point Pw, the processing means starts the analysis step with the waypoint preceding the point Pw, and so on until the waypoint for which a direct route exists.
    The processing means then displays on the screen an arrow direction general movement for a longer movement time (for example from 2 to 10 minutes or more). Such an arrow is useful for giving the trend of movement.
    According to one variant, the processing means determines the nearest point of passage of point Z and checks whether this point is in a circle of radius R 1 centered on a point of change of direction, R 1 is identical to or different from R, for example lower than at R, advantageously less than 0.75 R, for example between 0.5 R and 0.75 R. If the closest point is in the circle on the next point of change of direction (for example Pi + 2 for Figure 8 ), this point will be validated and the general direction of displacement will be determined on this point. If the nearest point is not in the circle on the next directional change point, the processing means will select the second closest waypoint for consideration to continue the step of determining the direction of travel.
